Egyptian Bass-Baritone Ashraf Sewailam is currently touring New Zealand performing in New Zealand Opera's comedy The Barber of Seville. The Christchurch season opens this week and while he's in town he decided to put on a FREE recital at the Christchurch Transitional Cathedral next Sunday afternoon, in response to the attacks on 15 March. He's joined in studio with conductor Wyn Davies.

New Zealand is one of the most wasteful places in the world - we produce more than 3 kilograms of waste each, every day.

Rather than wait around for someone else to fix the issue, a group of Raglan locals re-mortgaged their home to take over their town's waste management system. They created the organisation Xtreme Zero Waste in 2000, and it's still going strong. General Manager Dallas Butler is here to tell us what they've achieved.

3:10 Dr Katherine Foxhall and the history of migraines

Blood-letting, tying a dead mole to the head; these are just a few of the ways migraines have been treated over the centuries. The pain is so debilitating, patients have agreed to have holes drilled in their heads to stop it. One in seven of us will experience the misery of a migraine, and yet the disease is still misunderstood and difficult to treat effectively. Medical historian Dr Katherine Foxhall looks back on the history of migraine as a way to understand how we can move forward. Her new book is called Migraine: A History.
